Nagios has absolutely no knowledge of MIBs - basically all it know about
is hosts, services and their results... The problem you'll have is to
map a specific trap (or set of traps) to a Nagios service and alert
level with a meaningful message.
What's nice with SNMPTT is that it can parse MIBs and extract traps and
put everything in a SNMPTT config file ready for logging. You'll see the
traps, description and variables. All you have to do then is add an EXEC
line for the traps you want to send the result to Nagios, and set the
alert level and message you want (using the variables provided).
I attached a sample config file. This is basically a convert of IF-MIB
with two traps in it, linkUp and linkDown (I'm not sure it I trimmed it
of not...). What I added is the EXEC lines (and possibly modified the
FORMAT lines). Everything else is from snmpttconvertmib.

A linkDown trap signifies that the SNMP entity, acting in
an agent role, has detected that the ifOperStatus object for
one of its communication links is about to enter the down
state from some other state (but not from the notPresent
state). This other state is indicated by the included value
of ifOperStatus.

is recommended that values are assigned contiguously

must remain constant at least from one re-initialization of
the entity's network management system to the next re-
initialization."

then ifOperStatus should change to up(1) if the interface is
ready to transmit and receive network traffic; it should
change to dormant(5) if the interface is waiting for
external actions (such as a serial line waiting for an
incoming connection); it should remain in the down(2) state

A linkUp trap signifies that the SNMP entity, acting in an

notPresent state). This other state is indicated by the
included value of ifOperStatus.
